INVENTOR JERRY HEINIGE- United States Patent 3,447,467 EJECTION PUMP Jerry Heinige, 3311 S. Halsted St., Chicago, Ill. 60608 Filed May 5, 1967, Ser. No. 636,326 Int. Cl. F04b 23/04 U.S. Cl. 103-5 4 Claims ABSTRACT OF THE DISCLOSURE A pump comprising a generally tubular member having two sets of slanted openings therein, which openings are surrounded by hollow fittings connected to a common vacuum pump. The pump pulls a portion of the substance being pumped from the tube through one set of openings and forces the portion back into the tubular member at high velocity through the other set of openings. The openings are slanted in such a way that this action creates a flow of the substance through the tubular member.

This invention relates to a pumping device and more particularly to pumping devices which are versatile and eflicient in use and relatively simple and economical in construction.

Many pumps have been constructed which utilize a high velocity flow of fluid in a relatively large tube to draw more fluid along the tube at a lower velocity. These pumps may be used for deep pumping and for pumping substances which contain large objects which would be injurious to the ordinary vacuum pump. However, these pumps have been relatively inefficient, they have not been reversible, and they have normally been quite complicated in construction. The present invention is designed to overcome these handicaps and to provide an efficient, reversible pump which is safe, reliable, sturdy and relatively simple in construction.

An important feature of this invention relates to the provision of a reversible fluid ejection pump.

A second important feature of the invention relates to the provision of a fluid ejection pump which utilizes only the fluid being pumped and needs no extra reservoir of fluid.

Another important feature of the invention relates to the construction and position of the openings in the pumping tube.

Still another important feature of the invention resides in the provision of an ejection pump which will pump fluids containing large objects, passing the large objects without damage to the pump.

This invention contemplates other and more specific objects, features and advantages which will become more fully apparent from the following detained description taken in conjunction with the accompanying drawings which illustrate a preferred embodiment and in which:

FIGURE 1 is a partially cross-sectional view of a fishing device utilizing a pump constructed according to the principles of the invention.

FIGURE 2 is a cross-sectional view of a portion of the pump shown in FIGURE 1.

FIGURE 3 is a cross-sectional view tion of the pump shown in FIGURE 1.

Reference numeral in FIGURE 1 generally refers to a deep sea fishing device constructed according to the principles of this invention. The fishing device 10 comprises a large pear-shaped cage 11 having a wire-enclosed lower portion 12 and a Water-tight steel-enclosed upper portion 13, both of which are shown cut-away so that the contents of the cage 11 may be viewed. A metal ring 14 is fastened to the top of the cage 11 for raising and lowering the cage 11 out of and into the sea.

of a modified por- An ejector pump 16 constructed according to the principles of this invention is positioned at the bottom of the lower portion 12 of cage 11. The pump 16 comprises a lower threaded tube 17 which is positioned in a hole 18 in a round steel plate 19. The tube -17, as shown in FIGURE 2, is threaded into a lower fitting 21, which also has a lower end 22 of a center tube 23 threaded therein. An upper end 24 of center tube 23 is threaded into an upper fitting 26, which also has an upper tube 27 threaded therein. The threaded ends of lower tube 17 and upper tube 27 are inwardly tapered, and the ends of the center tube 23 are outwardly tapered, so that when the tubes are threaded into position, as shown in FIGURES 1 and 2, two slanting annular passages 31 and 32 are formed by the three tubes.

An annular inner cavity 33 in the lower fitting 21 surrounds the outer end of the annular passage 31, and a pipe 34 has a lower end 35 threaded into an opening 36 in fitting 21 to connect with the cavity 33. A second annular cavity 38 in the upper fitting 26 surrounds the outer end of the annular passage 32, and a pipe 39 has a lower end 40 threaded into an opening 41 in fitting 26 to connect with the cavity 38. Pipes 34 and 39 extend up through holes 43 and 44 in a large round metal plate 45 which divides the upper portion 13 and the lower portion 12 of the cage 11. The upper end of pipe 34 is connected to a T junction 47 which has one outlet connected through a valve 48 to a second T junction 49 and a second outlet connected through a valve 50 to a third T junction 51. The upper end of pipe 39 is connected to a T junction 53 which has one outlet connected through a valve 54 to the T junction 51 and a second outlet connected through a valve 56 to the T junction 49. T junctions 51 and 49 are connected to the input and output respectively of a centrifugal pump 57, which is bolted for support to a metal bar 58 fastened to a generally hemispherical metal cover 59 on the upper portion 13 of cage 11. A motor 61 is bolted for support to a metal bar 62 which is fastened to the cover 59. Motor 61 drives the centrifugal pump 57 by means of a motor shaft 63, and motor '61 is powered through a line 64 extending from a protective cable 65 which passes through the metal cover 59. A power wire 67 extends from cable 65 to control the valves 54 and 48, and another power wire 68 extends from cable 65 to control valves 56 and 50.

Metal frame bars 71-74 extend from the outer rim of the plate 45 down to the outer rim of the plate 19 to support plate 19 and to provide a framework on which a wire screen 75 is positioned to enclose the lower portion 12 of the cage 11.

In operation the fishing device 10 is lowered from a boat, barge or platform down into a deep portion of the sea. The motor 61 is then turned on to drive the centrifugal pump 57. Valves 48 and 54 are controlled to the shut, and valves 50 and 56 are open to transmit Water from the pipes 34 and 39 to the input and output respectively of pump 57. Thus, water is drawn from the lower tube 17, up through the slanted annular opening 31, the cavity 33, and the pipe 34 to the pump 57 where it is forced out through the pipe 39, the cavity 38, up the slanted annular opening 32 and into the upper tube 27. A continuous flow of water is forced to travel this course, and this causes a pressure condition in the ejection pump 16 which draws large quantities of water through the center of the tubes 17, 23 and 27 with considerable force. Since the opening in the tubes is relatively large, many fish, plants and other sea life will flow through the tubes and into the screened lower portion 12 of the cage 11, where they are trapped until the cage 11 is lifted out of the water and the objects are removed. Thus, a safe, efficient and reliable ejection pump 16 is provided for deep sea fishing on a commercial scale. The annular openings 31 and 32 are too small to admit objects of substantial size, yet these objects are forced through the large tubes .17, 23 and 27 into the cage 11. If, for some reason, the annular openings become clogged, or it is desired to reverse the direction of flow of the ejection pump 16, then valves 50 and 56 are closed electrically and valves 48 and 54 are opened, causing water to be drawn by pump 57 from the tube 27 through the opening 32, cavity 38 and pipe 39 and to be forced through pipe 34, cavity 33, opening 31 and down into tube 17. The pumping action of ejection pump 16 is thereby reversed, with no movement of parts in the pump 16 itself.

The absence of moving parts, the reversibility and the versitility of the ejection pump 16 are important features. It should be noted that a screen could be placed over the annular openings 31 and 32 if it is desired to limit even further the size of objects admitted into the pipes 34 and 39. The ejection pump 16 may be used for gnany different purposes, including dredging, deep sea research, and entertainment.

It will be understood that modifications and variations may be effected without departing from the spirit and scope of the novel concepts of this invention.
